Seated. thebores are. the ends ofafshaft. or bearing member 28,1 which is supported atits'mid-portion by a bearing sleeve 29v which terminates at"its opposite ends in yearticall.para1l'e1.flanges3'0;,and which is preferably int'eg'raliwith. and rigidly supported" by a vertical web 3l-,.a1so preferably integral with thefside por- -1 portions of the part 33 respectively abut the front pair of flanges 2'7, 30, and are of reduced diameter to define substantially cylindrical external journals, as at 35, 36, for a purpose to be described. At the lower end of the member is a transversely extending part 3'7, substantially in the form of a yoke which straddles the eccentric cam 13 and has oppositely disposed abutment members 38 which are spacedapart a distance equal to the diameter of cam means 13, and which bear against diametrically opposite points on means. 13 (see Fig. 3). The part 37 has laterally extending portions 39, 40 which are vertically slotted or--recessed, as at 41, to provide guide and lateral retaining means for driven ,jfollower'members 42, which are pivotally supported by the shaft 28 and are directly journaled and carried by hearing apertures 42 on the journals35', 36 for swinging movement both relative to and with ,the means 32, and in planes substantially parallel to theplane of movement of means 32. There are. preferably two members 42 on each of the jour-- nals 35, 36, the members 42 on each journal being.

offset, as at 43, respectively, rearwardly and forwardly and toward eachother so that thelower portions 44 of members 42 lie in a substantially common, substantially vertical planefsee Fig. 2). The members'42 on the journal 35 are inclined to each other, divergingdownward (see Fig. 3) to lie on opposite sides of shaft 4 and'seat in the directly opposite recesses 41 in portions 39, 40,

respectively. The bases 45 of the recesses 41 are substantially vertical, providing substantial abutment faces for cooperable driving engagement with inwardly faced vertical side portions 46 onmembers 42. Each of the members 42 has a lateral, outward extending flange or arm 4'7 having an upward facing shoulder 48 which cooperates with an adjustable driving abutment means 49, preferably a screw having its-head 50, which engages shoulder 48, provided with longitudinal serrations for a purpose to be described.-

At the top of member 32 and transverse thereto at the sides of bearing'part 33, are supports 51 which extend over the shoulders 48 and have in line therewith threaded apertures 52, in which the screw means 49 are adjustably threaded. On the underside of supports 51 are detent means 53, preferably spring pressed socketed plungers which engage, in the screw head serrations to lock the means 49 in'adjusted position. I I

Secured to'the underfac'e of the closure member 3, as by studs and nuts 54; are oppositely positioned pump members 55, each having a lat erally, downward and inward inclined pump cylinder 56 which communicates with a vertical inlet and discharge passage member 55. At the inlet end of passage 5'7 which opens substantially at the casing bottom wall, is a strainer element 58, preferably a; cylindrical screen of fine wire mesh closed at its bottom end. Within the passage 57 respectively below and above the communication of the pump cylinder therewith, are valve means 59', 60, preferably downward seating ball checks. At the discharge end of passage 5'7 which opens through member 3, is a valve 61, preferably a ball check, resiliently seated by a spring 61 held under compression by the tail nut sleeve 61*. The valve 61 is provided to prevent siphoning of oil from the casing 1 should a break occur in the oil feed line leading from the lubricator. The upper end of passage 5'7 terminates above member 3 in a,nipple'.62 for connectionby conduit'means'to the desired point of 5'7 extending throughof nipple 62 acting through the pump members is a shield 69 having a horizontal top portion and a depending continuous marginal flange or skirt 69 which terminates below the plane-of the inlet to passage 5'7. Within the casing is a heating means '70 which is positioned beneath the shield 69 and adjacent the passage inlet so that a quantity of heated fluid or lubricant will be maintained by the shield at the pump inlet for supply to passage 5'7. The means. '70 preferably comprises a steam conduit having an inlet '71 and anvoutlet 72 which open through the rear wall of the casing.

Positioned between the rear pair of flanges 2'7, 30 and cooperating with the cam-means 14, is a pump driving means similar to that above described as positioned between the front flanges 2'7, 30, and therefore the primes of the reference characters applied to the means cooperating with cam means 13 have been applied to the means cooperating with cam means. 14.

The operation of the device is as follows: Oscillation of drive sleeve 6 will rotate the shaft 4 carrying with it the cam means 13 and 14 which bearing against the late members 32 on shaft 28 through a complete reciprocation for each revolution of shaft 4. As the members 32 are moved or swing toward the left of Fig. 3, the left hand recess base portions 45 will engage portions 46 on members 42 and carry the members 42 therewith to effect the pressure stroke of the left hand pump plungers 63 through the connection between extension 68 and plunger head 66. As the left hand plungers 63 are moved through their pressure stroke, expelling fluid from passage 5'7 past valves 60 and 61 the right hand plungers .63 will be moved through their suction stroke, drawing in heated fluid to passage'5'7 past the valves 59. This is due to the right hand means 49'engaging the right hand shoulders 48, the means 49 being rigid with means 32. The rate of feed of the pumps or the stroke thereof is regulatable by the means 49, the amount of lost motion between the'head 50 and its shoulder 48, or the distance-therebetween, when faces 45, 46 are in engagement, determines the length of stroke of the pumps, that-is,-the setting of means 49 determines the extent to which the'plungers 63 will bewithdrawn from their respective cylinders on the suction stroke.

From the foregoing, it is apparent that each of the members 42 may have a different length of swing, and therefore impart to its pump piston 63 a different length of stroke due to the individualadjustment for each of members 42. It will also be noted that the pistons driven by means 13 travel ata greater rate than the pistons driven by means 14, so that there is a wide range obtainable between the discharge rates of the various pumps of the device.

Should air become trapped in any or all of the pump units, the tail nuts of nipples 62 may be loosened,thus relieving the spring pressure on the ball checks 61, so that the trapped air may be expelled upon manual operation of the lubricator abutment faces 38 will oscilpump unit or units; n
